Be it known that We, Howmfn D. Gemein und BUST A. ?ETEBSON, citizens of the United Saintes,` residing at Rockford.. in elle c'ounty of Winnebago and State of illinois, have invented certain new and useful linprovexnents inv 'liread-Board-Cleemng Apparatus, of which the following 1s a specim lient-ion.

ln the operation of s inning, lint and dirjt accumulate quite rupi ly upon the thread board. Such accumulation is objectionable for the reason that masses of lint sometimes drop onto the rotating bobbins and beenmeent-angled with the yarn being wound there on, while in other instances the bunches of lint are spun into the yarn and cause the -formation of gouts thereon. The usual method of cleaning the thread-board nus consisted in wiping itiby hand. several times a clay, using either a.. piece of waste el' a small board covered with plush 'or seine sixnilar material. ln order te clean the thread-board in this Way; the spinning 'frame must be shut down. and consequently there is a loss of production during the cleaning operatioi'a. When cleaning the thread-board manually, a great many. enrls are usually broken down, which causes :i further loss of production When the machine started. and also results in the produc tien of bad yarn clue to the piecingup of broken threads.

The object of this invention is to provide mechanical means for preventing the accumulation oi lint and the like upon the thx'ezulboux'ds unal tlnemlfguifles of n spinning frame.

The cleaning apparatus eolnpiiees. thie instance, two devis s i? fiig. arrnnggec te be reeiprocuteil over the upper suiaee oi the tluemllmaifls :incl the tlireaclguides of the spinning frame. Sani devices are nere in shown, by way of example, :is each Coniprising a roller 6 rotated through its con met with the thread-beeld :is the evice is traversed allang said board. the roller having :l peripheral llunge 'l' thatrolls upon t'ne th1emlbozu' l. The roller (i is o a gener-.illy conical form. the flange 7 being; at the inner. larger omi el ille roller. Vln this instance, the roller revered with a material 8 to which lin will readily cling, es, for ample. plush. The roller is rotatably mounted upon :1 spindle 9 lixecl to n. plate 10, said plate having means to engage a cleaner; traversing device to be later herein desfrilierl. Hinged lo the plate 10 at 11 is a hood l2, adapted to inclose tlieuppei part of the roller. 3) of tlie liooii abut against the plate l0 and tlius determine the operative position of the hood. The latter muy be liftecl by the op in elevation., tifa? The rear portions l2 (Figzl erativc when the ricaner reaches the end of its reciprocatory travel, or at any other time, and the roller cleaned by grasping the roller and drawing off the lint cllngxng to the piush 8.

The two cleaning devices, one for each side of the frame, are attached te an endls cahlell which is moved first in one direction and then in the other to traverse the cleaning devices back and forth upon the threadboards. The endless cable 13 is supported upon guide sheaves 14 so that opposite portions of the cablesr shall run longi tudinally of the thread-boards and adjacent to the inner edges of said boards and close to the frame of the machine.

At one end oi the spinning frame and ad jacent to one of the thx'eadeboards is located the mechanism for driving the cable, for reversing its direction of movement, and for arresting its travel at certain times. The driving and reversing mechanism 4is inclosed in a housing 15 secured to the spinning frame at one end of one of the sets of drawing rolls. Rotatably supported in said housing is a Shaft 16, one end of which projects outside of the housing and there carries a sheave 17 having two annular cable-receiving grooves therein. Attached to the spinning frame beneath the housing 15 is a vertically extending vguide rod 18 upon which is slidably mounted a pulley block 19 weighted as indicated at 20 and containing a sheave 21 over which the cable 13 extends in passing from one of the grooves in the sheave 17 to the other. The weighted sheave 21 serves as a tension device to take up, the slack in the cable 13 and keep it taut atail times.

Power is communicated to the sheave 17 to drive the cable, from the shaft of one 0f the drawing rolls. On said shaft is fixed a pinion 22 meshing with a gear wheel 23 which is loose on a shaft 24 in the housing 15. The gear 23 has a clutch hub 25 (Figs. 1S) and 20) adapted to coperate with a clutch pin 26 fixed on a geur wheel 27, the latter gear being fast on the shaft 24. Loose ori said shaft is a two-arm or bellcrank lever 28, one aim 28 of which carries a gear wheel 29, meshing at all times with the gear wheel 27. The other arm 28 of the bellcranh lever supports two intermeshing gears 30 and 31. the gear 31 being in constant mesh wt-h the gear 27. It will be seen that the ggar 27 will drive the gears 29 and 30 in opposite directions. Said gears 29 and 30 are arranged to engage alternately with a gear 32 (Figs. 15 and 16) fixed on the shaft 16 that carries the cable-driving sheave 17, whereby the cable is driven alternately in opposite directions. The bell-crank lever 28 is rocked to place the gears 29 and 30 alten nately in, mesh with the gear by means ycomprising an arm 33 pivoted on the shaft 24 and connected to the arm 28* by a tension memos spring 31. Fixed in the lever 28 is a stopR pin to limit relative movement between said lever and the arm in one fdirection. A stud 36 on the arm 33 is held against the periphery of a cam 37 by a torsion spring 38 surrounding the hub of the arm 33 and fixed at one end to said hub and at its, other to a Suitable fixed part, as 39. The cam 37 is operatively connected tb the shaft 24 through a gear train L1() 41 42 43 (Fig. 14). As the cam 37 rotates, the arm 33 will' be swung and the bell-crank lever 28 will be rocked to place the gears 2S) and 30 alternatcly in mesh with the gear 32 to drive the cable in opposite directions. It will be understood that the springs 34 and 38 give the gears 29 and 30 an opportunity to mesh properly with the gear 32 should the latter of said gears happen not to mesh at themoment of contact.

As indicated in Figs. 2 and 3, the rollers 6 are of such length as to overlie and clean the thread-guides c. The cleaners are therefore of such length as to project into the region of movement of the separators e. The latter, as is usual, are fixed to bars f extending longitudinally'of the spinning frame, said bars being vertically reciprocated by appropriate mechanism (not shown). If the travelin movement of the cleaners were continued a vter the separators c are raised far enough to extend into the spaces between the thread-guides c, the cleaners might coll' e with said separators. We therefore preferably provide means for arresting the travel of the cleaners at the proper times to avoid interference with the separators,V

27. 0n one end of the shaft 4.4 is fixed an arm 46 (Fig. 10) having a stud'47 lying within a cam slot 48 in a cam 45) pivotcd to the housing at,50. The cam 49 is rocked by an arm 51 connected by a link to one` arm of a lever 53 (Figs. 2 and 9). The lever is pivoted upon a pin 54 adjustably fixed in a bracket 55 attached to the spinning frame. The other arm of said lover carries a weight 5G and extends into the path of movemeri't of one of the bars f. As the bars f are raised. the adjacent bar tilts the lever 53, thereby operating the lever 45 to disconnect the gear 23 from the shaft 24, and stopping the cleaning apparatus. When the separators c have descended below the plane of the threadguides c, the weight 56 operates the shifting lever 45 to drive the cable 13. 53* (Fig. 9) is an adjustable stop to ,limit the starting movement of the lever 53.

The cleaners 5 may be connected to the cable 13 by any suitable means. but preferum :Jard Qi? abi@ beneath the u meh side of h@ mnchme.
